Gen Vehicle Protocol Tool¶
It’s a convinent tool to let you quickly generate a nearly complete code for a new vehicle. You only have to do is to have the dbc file (which is a communication protocol for the car, which is usually made by the vehicle integrated company), and write a less 10 lines config for generate an encode/decode `
Dependency¶
sudo pip install pyyaml
Usage:¶
The tool’s input is :
vehicle dbc file: like lincoln’s dbc file, put it under this foldergenerator tool config file: for an example, a lincoln’s is lincoln_conf.yml, detail you can see the example file of lincoln_conf.yml
Run:
python gen.py lincoln_conf.yml
Tool Framework¶
gen.py: a central control the overall generating progress and will call the scripts belowextract_dbc_meta.py: extract dbc info to an internal generator tool used yaml config, which will include a protocol name, id, how many vars in a protocol, every var’s name, type, byte start, bit_start, bit_len etc. When we have these info, we can automitally generate code as we wish.gen_protoco_file.py: generate a proto file for this vehicle, which is used to store parsed info from CAN frame using these generated code.gen_protocols.py: generate protocol code (encoding and decoding CAN frame)according to the extract dbc meta.gen_vehicle_controller_and_manager: generate vehicle controller and vehicle message manager according to our recent chassis canbus framework.
